摘要:
An applicator (10a) affixes fitments (12) to paperboard cartons (20), each fitment (12) comprising a screw cap on a pour spout. An ultrasonic horn (18) reciprocates between a retracted position for receiving a fitment (12) and an advanced position for depositing the fitment (12) on an outer surface of a carton (20). A duct (26) extends and provides fluid communication between an air handler and a fitment-holding recess (30) formed in the horn (18). The air handler is actuable to evacuate the duct (26) to retain a fitment (12) in the recess (30) by suction while transporting the fitment (12) to be affixed to the container wall. The air handler also supplies pressurized gas to the duct (26) to blow the fitment (12) from the horn (18) before the horn returns to the retracted position. A receiver reciprocates between a pick-up position for receiving a fitment (12) and a delivery position for passing the fitment (12) to the horn (18), the receiver comprising a head (34c) with a suction opening (40a) formed in the end portion thereof for communication with the interior of the fitment.
摘要:
Associated with a form-fill-seal packaging machine for liquid-packaging cartons is an apparatus (10) including a pusher (24) for driving a pour spout fitment (12) axially from a removal-ready position at an exit end (14) of a feed track (16) that serially guides pour spout fitments (12, 30) edge-wise to the exit end (14) such that external, circumferential flanges (18) of adjacent pour spout fitments (12) and (30) tend to overlap one another. The apparatus (10) also includes a pour spout fitment separator (28) supported adjacent the exit end (14) for reversing an immediately following pour spout fitment (30) back along the track (16) to a position where the flange (18) of the leading fitment (12) in the removal-ready position and the flange (18) of the immediately following pour spout fitment (30) do not overlap.
